I would strongly recommend Dreamweaver. I have been using it for over 10 years now and the latest version CS4 is superb. Not only do you get WYSIWYG editing but also split mode or code only views. Integration with CSS it is also excellent. You can get a 30 day free trial from the Adobe website.
If you were looking for a free HTML editor, Evrsoft 1st Page 2000
is well worth a look.
Let me know if you need any more info.
